[Plugin: WordPress SEO by Yoast] A lot of bugs in newest version

WordPress version: 3.4.1
WordPress SEO version: 1.2.7

I did this: I installed WordPress SEO 1.2.7 (After that I instaled back version 1.1.9 because it seems to WORK).

I expected the plugin to do this: Work good.

Instead it did this:
#1 The auto meda description for posts is replacing words like ă,Ă,ș,Ș etc with ? (question mark character).
#2 Now Facebook Open Graph has single quotes and I think you should put double quotes.
#3 Why are there two meta descriptions? One for Open Graph and a normal one. Why not use a single one
<meta name="description" content="Welcome to WordPress. This is your first post. Edit or delete it, then start blogging! a." property="og:url"/>.
#4 Displaying this http://i45.tinypic.com/k49kb9.jpg . I want to hide it.
#5 It has too many menus and the options are not well organised, in my opinion.
#6 Improve your Site!, Need support?, Spread the Word! should be more discret or better organised because they take too much sapce.
#7 On the Titles & Metas the Help page content should be visible from the Post Types, Taxonomies and other page.
#8 Plugin should be plug and play. What I mean is that Meta description template: on the Post Types should be populated with %%excerpt%%.

This plugin was great until 1.2.0 but don’t know what happened. It should be extremely easy to use for non IT users and should have better organised options. Now, it’s a mess.
